CALL METHOD

Short Reference

Syntax Forms

Static Method Call

1. [CALL METHOD] static_meth(parameter_list ).
   CALL METHOD  static_meth parameter_list.

Short Forms

2. [CALL METHOD] { static_meth( )
                |static_meth( a )
                |static_meth( p1 = a1 p2 = a2 ... ) }.

Chained Method Call

3. {oref->}|{class=>}meth1(...)->meth2(...)->...->meth( parameter_list ).

Dynamic Method Call

4. CALL METHOD dynamic_meth {parameter_list
                          | parameter_tables }.

Effect

Method call in ABAP Objects. There is a difference between a static method call, in which the methodID must be fully known in the program, and a dynamic method call, in which the method ID is determinedentirely or in parts at runtime. The static method call can be executed in different forms. In one form,the parameters are passed in a parenthetical expression, in the other without a parenthetical expression.For the parenthetical expression, short forms are allowed. You also have the option of chaining methods.In dynamic method calls, you are not allowed to specify the parameters in parentheses and you must use the statement CALL METHOD.

When you call an instance method using a reference variable and the static type of the reference variableis a superclass of the dynamic type, then you can use the dynamic method call to call all visible methodsof the dynamic type, whereas with the static method call, you can call only the visible methods of the static type.

System Fields

The system field sy-subrc is set to 0 when a method is called. If anon-class-basedexception is raised that was handled by the assignment of a value, then sy-subrc is set to this value.

Note

Functional methods can not only be called with CALL METHOD, but also atoperand positions for functions and expressions.
